Description

Silent Diesel Generator Set

technical field

The utility model belongs to the manufacturing field of diesel generating sets, in particular to a silent type diesel generating set.

Background technique

Diesel generator set is a kind of power generation equipment with diesel as the main fuel. The diesel engine is used as the driving force to drive the generator (ie electric ball) to generate electricity and convert kinetic energy into electrical energy and thermal energy. The whole set of diesel generating set is mainly divided into three parts: diesel engine, generator and controller.

At present, most of the solutions to the heat dissipation of silent diesel generator sets are provided with air inlets and air outlets on the silent cover of the unit. Most of the noise problems are solved by adding traditional noise reduction and sound absorption structures to the unit. Although this traditional structure can play a certain role in reducing the noise of the unit, this structure sacrifices the internal ventilation of the unit in exchange for reducing the emission noise. This affects the heat dissipation performance of the diesel generator set, which in turn leads to a large power loss of the unit.

detailed description

The utility model is described in further detail below in conjunction with the accompanying drawings.

Referring to Figures 1-9, a silent diesel generator set in this embodiment mainly includes an engine 1, a generator 2, a silent cover 16, and a unit chassis 3, and both the engine 1 and the generator 2 are fixed on the unit chassis 3 and is isolated from the external environment by the silent cover 16. Two air inlets and two air outlets are arranged on the silent cover 16, including the first air inlet 4 and the first air outlet 6 opened on the engine 1 side, and the opening At the second air inlet 5 and the second air outlet 12 on the side of the generator 2, the air inlet and the air outlet adopt a louver structure to prevent dust and rainwater from entering the unit. Near the inside of the first air inlet 4, an axial flow fan 10 is arranged, and the axial flow fan 10 is installed in the inside of the quiet cover 16 through the axial flow fan partition 17. The coolant in the radiator 11 on the plate 18 is effectively cooled, and the hot air is discharged from the first air outlet 6. The radiator 11 is arranged inside the silent cover 16 and passes through the water inlet pipe 19, the water outlet pipe 20 and the coolant jacket of the engine 1. Pipe connection, under the action of the hydraulic pump driven by the engine 1, the coolant circulates between the coolant sleeve of the cylinder of the engine 1 and the radiator 11, and the heat generated by the engine 1 is discharged to the air through the coolant and the radiator 11 During the process, the engine 1 is cooled and dissipated. The radiator 11 is arranged at a certain inclined angle relative to the air outlet of the engine 1, so that the contact area of the radiator can be increased, and the engine can be better radiated heat;
